Hiddenhurst is the former estate of businessman Thomas Hidden, on Sheffield Hill Road in the Town of North East, New York, United States, south of the village of Millerton. It is an elaborate frame house built at the beginning of the 20th century in the neo-Georgian architectural style. Hidden created the estate from portions of four dairy farms in the area and used it to breed horses. After his death in 1918, most of the property was acquired by another large dairy farm in the area, which demolished most of the horse-related facilities. The house is considered one of the most architecturally significant in eastern Dutchess County. In 1991 the remaining estate property was listed on the National Register of Historic Places. It is also a contributing property to the Coleman Station Historic District created two years later. Building Hiddenhurst is a complex of three buildings on a lot on the northside of Sheffield Hill, a half-mile (1 km) west of the Connecticut state line. The lot is sheltered by planted woodlands of copper beech and pine, especially on the north and west sides. It is on a high ridge over Webutuck Creek to the west. The other properties in the area are farms, with much open land offering views into the Harlem Valley to the south and the Taconic Mountains to the north. The main house retains its historic and architectural integrity. To its south is an L-shaped two-story frame hipped-roof clapboard-sided caretakers' house with a gabled wing joined by a breezeway to a garage. At the Northwest corner of the property is a one-story guest house of contemporary shingle design. Neither is considered as contributing to its historic character. To the west is a swimming pool, also non-contributing as it is of more modern construction. A tennis court, pond and a water garden was added on the western side of the property in the 1980s. Exterior The house is a two-story, three-bay clapboard-sided structure with a hipped roof resting on a large plinth block of undressed ashlar masonry. This foundation also supports a wooden veranda that completely surrounds it. It is bounded with a balustrade featured paneled corner columns and balusters with extremely narrow necks compared to their bellies. Trellised entrances supported by paired Corinthian columns break it on the east and west sides. At the center of the south (front) facade, the balustrade is broken by the
